I guess we’ll see how it plays out, but my guess would be that Georgia isn’t quite where Ukraine was yet, and hence why they want to prevent that eventuality while that’s still possible to do. Wanting to join EU and wanting to be sovereign are two separate concerns. Clearly, sovereignty is becoming a sharper issue than joining the EU right now. The picture that the interview I linked above paints is pretty wild, so I don’t really find it surprising that they want to put an end to that. Also, the fact that EU politicians have been prancing at the rallies against the law kind of gives the game away.
